A MULTIMILLION dollar four-storey office building on Phnom Penh's Sihanouk Boulevard is still on the market after five months, said Sen Chan Rietrey, executive director of Cambodia Estate Agent (CEA), which is handling the sale. The building is owned by a Singaporean firm, he said, declining to give the name. The owner is asking US$2.3 million. It went on the market on June 15.
